As modern-day dentists, we are 

faced with a complex set of treat-

ment decisions, compelling us to 

continually weigh the available 

therapeutic choices as we push 

toward optimal patient care com-

bined with eff cient and prof table 

clinical practices. Endodontic 

treatment is one area of dentistry 

in which the options are plentiful 

and varied, often leading us to 

ponder how best to provide con-

servative, predictable root canal 

treatment that offers long-term 

solutions. 

To achieve this goal, we must 

begin with confidence in our 

instrument system and technique. 

The right mix yields a therapy 

based on the ideal combination 

of safety, simplicity and sophis-

tication. In selecting a treatment 

system, most clinicians aim to 

find reliable instruments that 

offer comfortable handling, per-

form appropriately, and, ideally, 

expedite treatment. The follow-

ing three cases demonstrate the 

treatment of common endodontic 

problems using Komet USA’s new, 

two-f le F360™ NiTi endodontic 

file system. The instruments in 

the system feature a thin-core, .04 

taper, S-curve design that provides 

outstanding cutting efficiency 

while respecting natural root 

canal morphology. Although most 

cases can be completed using the 

.04-taper, sizes 25 and 35 f les, the 

system also accommodates larger 

canals by offering additional .04-

taper f les in sizes 45 and 55. 

Case one: Right 

maxillary canine 

The patient presented with acute 

pain and reported a feeling of 

swelling in his face. Tooth No. 6 

was sensitive to percussion, but it 

did not demonstrate sensitivity to 

air, sweets or temperature stimuli. 

Following a discussion of the treat-

ment options, the choice was made 

to perform endodontic therapy on 

the tooth to eliminate the pain. The 

prescription for definitive treat-

ment was a post and core with a

01

STEP

A pre-operative radio-

graph was taken (

Fig. 1).

02

STEP

Local anesthetic was 

administered, and digital working-

length measurements were taken 

and recorded for initial working 

length.

03

STEP

To ensure a straight-line 

visual access to the canal, a #6 

rou nd d i a m o nd bu r (68 01.

FG.018), operated at high speed, 

was used from the lingual aspect. 

04

STEP

The coronal portion of 

the canal was opened with the 

AK10L19 pre-enlarger f le. Note: 

To reduce fracture risk, this file 

should be employed only in the 

straight coronal portion of the 

root canal; it is used in place of 

multiple Gates-Glidden burs. 

05

STEP

A smooth glide path was 

developed with a #15 K-f le, and the 

working length was verif ed with an 

apex locator to 29 mm. 

06

STEP

The canal was shaped 

with the F360™ .04-taper, size-25 

rotary f le while a water-soluble gel 

was administered to the 29 mm 

working length. Note: The hand-

piece should be set for 1.8 Ncm 

torque value at 350 rpm. To elimi-

nate the risk of separating the f le, do 

not attempt to expedite negotiation 

of the canal by increasing the rpm.

07

STEP

Using copious amounts 

of water-soluble gel, the canal was 

prepared with the F360™ size 35 

rotary f le (.04 taper) to the 29 mm 

working length.  

08

STEP

The canal was irrigated 

with sodium hypochlorite, and 

the irrigant was allowed to sit for 

60 seconds. 

09

STEP

The DENTA 2™ CO2
